Spring Migrant Wildlife Walk

Intro by Tom

 The Yale West Campus Wildlife Walks are more of an event than just a walk.  On April 25th (Friday) a gathering of 35 excited nature enthusiasts met at the WC Conference Center thanks to the organizers, Yale Peabody Museum and Yale West Campus Administration.  With a quick introduction from Tom Parlapiano (YPM) and lesson on how to use binoculars for the newbies, we set off across campus.  Myself (Lynn), Mark Aronson (YCBA), Jim Sirch (YPM-retired), and Cody Limber (EEB) headed out to find what migrant birds species might be using campus as a refresh stop.  Entering into the nature trails the group quickly thinned out into a long line of folks looking in all directions for any sightings.  

Bird Watchers

Some West Campus residents let us know they were around and are just as important as the migrants, Northern Cardinal, Brown-headed Cowbird, Carolina Wren, and American Crow making a showing.  Once we navigated under West Campus Drive along the stream, things began to pick up a little.  A pair of Mallards were in the river, a Song Sparrow sang from a flowering cherry tree, and distant Red-winged Blackbirds called us toward the farm.  

Another birdy stop along the way, Cody gently persuaded a Yellow Warbler out into the open to show the walk participants their namesake colorful feathers.  A Fish Crow called out it's telltale laugh "ha-ha" as it flew overhead checking out the humans below.  Rounding the corner out toward the barn, a pair of Yellow Warblers chased each other about putting on a show.  A cooperative American Robin sat out in an opening in a tree allowing birders a chance to easily perfect their binocular skills.  Brown-headed Cowbirds and Common Grackles, also gave nice views and showed off.

Although the walk finished at the Farm, spectators continued to enjoy birding, while snacking, with special sparrow visitors (Swamp Sparrow, Chipping Sparrow, White-throated Sparrow and Swamp Sparrow).  A Red-shouldered Hawk flew overheard and a distant Warbling Vireo sang to let us know they were back on campus.  An amazing group, who altogether found 35 species on the walk and another 7 while walking back to work.

New Friends, New Post, New Bird!

 On Friday, May 3rd, Yale affiliated folks joined an official West Campus Bird Walk led by Peabody Museum and colleagues in conjunction with Yale West Campus Administration's program, Belonging Plan. Around 20 individuals gathered at the conference center and after quick introductions by the birding team, we set out across campus, winding our way to the West Campus Barn.

Making our way through the common areas and parking lots, we tallied many year-round residents on campus before making it to the nature trails and our first migrants.   Black-throated Green Warbler and Northern Parula (warbler) were singing from the tree tops.  As we moved along the trail, one of the Black-throated Greens came down low and close enough to give many participants very nice looks.

Heading closer to the barn, we experienced a nice push of lower canopy dwellers.  These are birds that usually nest within 15 feet of the ground, including Warbling Vireo, Yellow Warbler, Blue-gray Gnatcatcher, House Wren, and Swamp Sparrow.  Tom Parlapiano of the Peabody had the entire group stop and just listen at one point, trying to count how many different birds they could hear singing all at once.  Almost everyone could hear about 10 different bird species and multiple individuals.

Once we made it to the barn and had some lovely refreshments, Alex Lin-Moore (Yale Graduate Student, 2023), informed us of a very nice bird.  He had just spotted a White-eye Vireo, a new species for our West Campus list (number 137)!!!  White-eyed Vireos have recently been found in higher numbers throughout the state, with several individuals being spotted, but are a more southern species.  Again this bird was quite vocal and made a number of appearances so that many participants were able to see it.

Birds Saving Birds

Fall migration is a great time of year and it's also a horrible time of year, at least when talking about the casualties from birds colliding with windows.  But this time, the same sad story we repeatedly tell has a happier ending.  

The simple fact is that birds do not see the same way that we do.  Glass and windows can either be invisible to birds when it's a hallway with windows on both sides or an illusion, when all they see is nature reflecting.  Besides, I'm pretty sure we've all seen a human walk into a glass door anyway.  Birds fly into glass and die.  Some times they bounce off and may fly away only to pass hours later.  Hopefully a few manage to go off and live their birdy lives.  Estimates about how many birds die from window collisions every year around the world range up to the billions.  

There have been lots of changes to West Campus over the past 10 years and some of the methods we used to prevent birds from flying into the glass at the Collection Studies Center are no longer appropriate.  So while we continue to search for a more permanent, continuous, economical, sustainable solution to the problem, this is what we have done and it's working. 

Thanks to support from CSC administration, IPCH, and the Yale Peabody Museum, WC birders have installed laminated photographs along the most deadly windows in the building.  The sheets have nature images (mostly birds) on one side and various bird silhouettes on the other to create a pattern to break up reflections.  The laminated sheets can be temporarily put up during peak migration and be reused!!! While there are some issues with an installation like this to deter collisions, it seems to be working quite well. 

The silhouettes sides are mostly facing out to break up the reflections, the tree in the window is still a reflection. 

In the seven days leading up to the photos going on the windows we had 15 dead birds along these windows.... 15!!  That's more than 2 per day.  

Birds from the 3 days before the installation...

Birds from days 7-4 before installation (2 other juncos are not included)

And since the photos have been up....  no photo because no dead birds! 

While this is fantastic news, there are still other places on West Campus that still have high collision rates.  But we are super excited in the CSC that we are able to find ways to be environmental ambassadors to our avian co-habitators and are excited to look for methods to remedy this problem around campus. 

View from inside.  The corridor is no longer see (or fly) through.

A special shout out to Beth Bolen  and Laurie Batza for all their support with this.  0 birds in 7 days.  Keep the good news coming and thanks for all the positive comments!!! 

A Christmas Goose

As we all preparing for the excitement of the winter break, residents of West Campus were treated with a special holiday present, a new bird!  Our last new bird for the campus list was last spring over, just about a year and a half ago.  As our list climbs, it's been tougher to find species we haven't yet seen but we have a little bit of end of the year luck.

Snow Goose- young bird, adults are white with pink bill and legs

Monday evening I first spotted a different goose among the Canada Geese but wasn't able to ID it in the dark or take photos.  I came prepared the next day but to no avail, no goose.  Then yesterday, a member from the YU Art Gallery, stopped to ask me about the 'other goose'.  So I grabbed my camera and went on a goose chase.  Not so wild, I relocated the bird in a couple of minutes and took some photos.

Grabbing a snack along the way.

After some help from friends on Facebook, the bird was verified to be a juvenile Snow Goose!  Snow Geese breed in the Arctic and migrate south along flyways to the southern US.  The major flyway is through the middle of the country but a smaller population flies along the east coast to overwinter in Virginia/North Carolina.  Sometimes these birds will take quick stops along the way, including in Connecticut and this year we seem to be popular.

Size comparison with a Canada. Probably a 'Lesser' Snow Goose based on size.

All the birder on campus are excited about this new find and the gaggle seems to be fairly acclimated to people.  Next time you see the geese take a look to spot the smaller white one before it decides to head on south.

A Break from Birds: Insect Addition

 A special post today about the recent Nature Walk hosted by the Peabody Museum West Campus Education Center.  On June 19th Tom Parlapiano organized a nature walk at West Campus focusing on insects that was lead by Peabody entomology collection manager Dr. Raymond Pupedis.

Ants quickly moving their pupae after their nest was disturbed.

Heading from the nursing school over to the trails by the West Campus Farm, Dr. Pupedis illustrated a number of ways that insects can by collected for study.  He demonstrated the techniques of 'sweeping' using an insect net through foliage, 'beating' a branch to make insects fall onto a white cloth, and the 'pooter' or aspirator that uses an apparatus to suck up the insects into a collecting jar.

Tom took a swing with the net.

An insect temporarily placed in a vial made it easy for participants to see.

Participants at the walk were able to see insects up close and learn about their natural history and techniques to help identify species.  They learned that it's possible to identify different wood-boring beetles based to the patterns left behind by larvae from feeding.

Questions about the damsel fly being lightly held in hand.

Dr. Pupedis had also set up two light traps the evening before and described how the different traps worked.  The insects from the traps were then put out on the sheet for everyone to examine.  Even though it was relatively 'slow' for insects that day, at least 100 different species of insects were seen.  A species "Thank You" to Dr. Pupedis for leading the walk and to all the participants who came!  Now back to the birds.
